I stumbled upon a stray Contender 18" Bullberry tapered barrel in 7mm TCU today and I think it followed me home and will show up on my door step next week. Any ideas on what I can feed it?? Maybe with IMR 4895.

I have lots of info on 10" pistol loads, but I can't find anything that is meant for an 18" or so. I was planning on starting with Speer 115 gr HPs in commercial cases. I'm using the 115 HPs in my 15" 7mm-08 Encore and they slap deer down real well....i know the velocity will be less with the TCU, but it may work there as well.

Any info will be appreciated!!!
